机床行业使用液压系统来提供能量和力来执行各种金属加工操作。液压系统使用许多不同类型的液压元件，如液压泵、插装阀、伺服系统、微处理器，甚至液压机器人。一份典型的清单将包括10个优化系统操作的重要领域:阀门分析和流体选择；液体的储存和处理；污染控制；高温如何影响操作；系统维修期间引入的污染物；从失败中学习；泄漏控制；系统设计考虑；回收程序和流体维护程序。本文是前一篇论文MSR80-09的更新。

THE MACHINE TOOL INDUSTRY USES HYDRAULICS TO PROVIDE THE ENERGY AND FORCE TO PERFORM THE VARIOUS METALWORKING OPERATIONS. HYDRAULIC SYSTEMS USE MANY DIFFERENT TYPES OF HYDRAULIC COMPONENTS, VARIANCE PLACEMENT PUMPS, CARTRIDGE VALVES, SERVOS, MICRO-PROCESSORS AND EVEN HYDRAULIC ROBOTS. A TYPICAL LIST WOULD INCLUDE 10 IMPORTANT AREAS OF INTEREST FOR OPTIMUM SYSTEM OPERATION: VALVE ANALYSIS AND FLUID SELECTION; STORAGE AND HANDLING OF FLUIDS; CONTAMINATION CONTROL; HOW ELEVATED TEMPERATURES AFFECT OPERATIONS; CONTAMINANTS INTRODUCED DURING SYSTEM REPAIR; LEARNING FROM YOUR BREAKDOWNS; LEAKAGE CONTROL; SYSTEM DESIGN CONSIDERATIONS; RECLAMATION PROCEDURES, AND FLUID MAINTENANCE PROCEDURES. THIS PAPER IS AN UPDATE OF PREVIOUS PAPER MSR80-09.
